Since I am not able to change my post, I just saw that I have a fragment inside of it of smt I was trying.
.Editable(e => e.Mode(GridEditMode.InLine))
Shoud of course by
.Editable(e => e.Mode(GridEditMode.InCell))
I tried InLine to see if it works, but I doesnt fit my needs, I need InCell, so I dropped it
